The magician begins by taking out 9 cards. A spectator then freely cuts off a packet, counts the cards, and remembers the card at that corresponding number. After that, the spectator freely selects 3 cards from the 9, and the sum of those values not only locates the original selection but also reveals the other three cards of the same value.
A classic principle reworked with a special setup turns this into a much stronger ACAAN-style routine.
